MAS/MILS sequence number 0020930025 (Bureau of Mines, 1995). Site is in Lake Clark National Park and Preserve. This unnamed occurrence may actually be the Neacola River occurrence (ARDF number LC001).
Location: On or near the mountaintop in the Neacola Mountains that is about 11.3 km SW of peak 6,805 (Neacola River occurrence - ARDF number LC001). Located in the NW corner of the Lake Clark D-1 quadrangle; occurrence #5 of Lambeth (1978). Location is only known within 5 km.
Geology: Lambeth (1978) described the occurrence as coarse molybdenite with tungsten in fracture in quartz monzonite. Nelson and others (1983, unit Ti17) described the bedrock as granite and biotite-hornblende granite and granodiorite. Potassium-argon dates from samples of unit Ti17 range from about 35 to 41 m.y. (Reed and Lanphere, 1972; 1973). The rocks in the south seem to be younger than the rocks in the north (Nelson and others, 1983).
Workings: Unknown
Age: Mineralization is Tertiary or younger. Potassium-argon dates from samples of this plutonic body range from about 35 to 41 m.y. (Reed and Lanphere, 1972; 1973).
Alteration: Unknown
